Hi there, I've just been playing around with a vehicle with a motor for each of the two main wheels. If I don't load the RCX with anything else than these two motors and set their respective speeds to 0 and 7, it drives in a nice circle with a small (...)

If you downloaded leJOS 1.0.2.RC6 you should download and install 1.0.2.RC8 instead as there is a bug in RC6 that causes the RCX to ignore sensors and buttons for several minutes. Apologies for the inconvenience - Paul Andrews. (25 years ago, 2-Sep-01, to lugnet.robotics.rcx.java)
